Gates 19187 HVAC Heater Hose - Heater To Intake Manifold

Gates 19187 Molded Heater Hose Overview

The Gates 19187 molded heater hose is a factory-molded, OE-style coolant hose built for tight engine bays where a straight hose will not route correctly. It is made from EPDM and is approved for coolant, water, air, and marine applications.

Compatible With 1995-1999 Nissan Sentra and 1995-1998 Nissan 200SX heater-to-intake-manifold routing, this molded heater hose follows the original path for a cleaner, more accurate replacement. Gates Molded Heater Hose 19187 is shaped for smaller, tighter-fitting engine compartments.

• Degraded hose shape affecting heater circuit routing

Installation Notes and Tips

Verify the hose path, end diameters, and centerline length before installation. This application notes that a protective sleeve is required. Inspect adjoining clamps, fittings, and intake-manifold connections for wear or corrosion before transferring the hose into service. Gates 19187 should be routed to match the original heater-to-intake-manifold layout on the vehicle.
